mathsurgery - Equations formulae, identities and expressions 3 year 8

All
• Use simple formulae from mathematics and other subjects; substitute positive integers into linear expressions and formulae and, in simple cases, derive a formula
• Simplify linear algebraic expressions by collecting like terms; multiply a single term over a bracket (integer coefficients)
• Construct and solve simple linear equations with integer coefficients (unknown on one side only) using an appropriate method (e.g. inverse operations)

Most
• Use formulae from mathematics and other subjects; substitute integers into simple formulae, including examples that lead to an equation to solve; substitute positive integers into expressions involving small powers, e.g. 3x2 + 4 or 2x3; derive simple formulae
• Simplify or transform linear expressions by collecting like terms; multiply a single term over a bracket• Construct & solve linear equations with integer coefficients (unknown on either or both sides) using appropriate methods (e.g. inverse operations, transforming both sides in the same way)

Some
• Use formulae from mathematics and other subjects; substitute numbers into expressions and formulae; derive a formula and, in simple cases, change its subject
• Simplify or transform algebraic expressions by taking out single-term common factors
• Construct and solve linear equations with integer coefficients (with and without brackets, negative signs anywhere in the equation, positive or negative solution)
